Microsoft Internet Explorer 5.01, 5.5, and 6, when using an HTTPS proxy server that requires Basic Authentication, sends URLs in cleartext, which allows remote attackers to obtain sensitive information, aka "HTTPS Proxy Vulnerability."

Multiple design errors in Microsoft Internet Explorer 5.01, 5.5, and 6 allow user-assisted attackers to execute arbitrary code by (1) overlaying a malicious new window above a file download box, then (2) using a keyboard shortcut and delaying the display of the file download box until the user hits a shortcut that activates the "Run" button, aka "File Download Dialog Box Manipulation Vulnerability."

Microsoft Internet Explorer allows remote attackers to bypass cross-domain security restrictions and obtain sensitive information by using the @import directive to download files from other domains that are not valid Cascading Style Sheets (CSS) files, as demonstrated using Google Desktop, aka "CSSXSS" and "CSS Cross-Domain Information Disclosure Vulnerability."

The FTP client in Windows XP SP1 and Server 2003, and Internet Explorer 6 SP1 on Windows 2000 SP4, when "Enable Folder View for FTP Sites" is enabled and the user manually initiates a file transfer, allows user-assisted, remote FTP servers to overwrite files in arbitrary locations via crafted filenames.

Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, including (1) devenum.dll, (2) diactfrm.dll, (3) wmm2filt.dll, (4) fsusd.dll, (5) dmdskmgr.dll, (6) browsewm.dll, (7) browseui.dll, (8) shell32.dll, (9) mshtml.dll, (10) inetcfg.dll, (11) infosoft.dll, (12) query.dll, (13) syncui.dll, (14) clbcatex.dll, (15) clbcatq.dll, (16) comsvcs.dll, and (17) msconf.dll, which causes memory corruption, aka "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2087.

Unknown vulnerability in Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to obtain information and possibly execute code when browsing from a web site to a web folder view using WebDAV, aka "Web Folder Behaviors Cross-Domain Vulnerability".

Unknown vulnerability in Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to execute arbitrary code via a web site or an HTML e-mail containing a crafted JPEG image that causes memory corruption, aka "JPEG Image Rendering Memory Corruption Vulnerability".

The JPEG decoder in Microsoft Internet Explorer allows remote attackers to cause a denial of service (CPU consumption or crash) and possibly execute arbitrary code via certain crafted JPEG images, as demonstrated using (1) mov_fencepost.jpg, (2) cmp_fencepost.jpg, (3) oom_dos.jpg, or (4) random.jpg.

Internet Explorer 5.01 SP4 up to 6 on various Windows operating systems, including IE 6.0.2900.2180 on Windows XP, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, as demonstrated using the JVIEW Profiler (Javaprxy.dll). NOTE: the researcher says that the vendor could not reproduce this problem.

Microsoft Internet Explorer 6 SP2 (6.0.2900.2180) crashes when the user attempts to add a URI to the restricted zone, in which the full domain name of the URI begins with numeric sequences similar to an IP address. NOTE: if there is not an exploit scenario in which an attacker can trigger this behavior, then perhaps this issue should not be included in CVE.
